NATRONA — A district attorney and police chief are reviewing a pattern of violence at a bar that saw one patron stabbed and another shot to death outside within 24 hours.

Allegheny County District Attorney Stephen Zappala Jr. is speeding up a review of the problems at Granma's Inn in Natrona.

Police Chief Mike Klein said police have made drug arrests, and know of at least nine fights and 10 other disturbance calls at the bar in the last year.

Police arrested a man with stabbing another man outside the bar about 10 p.m. Wednesday. About 22 hours earlier, 32-year-old Jerico Jones of New Kensington was shot to death. Nobody is charged in that shooting.
